Seafood is a global commodity traded worldwide that follows a long, non-transparent and complicated supply chain. Seafood fraud and adulteration has been an emerging topic discovered during the past decade. According to a recent survey, 69% wild pacific salmon on the market was indeed farmed Atlantic salmon. In comparison to other techniques, advanced spectroscopic techniques have unique advantages in tracing food fraud and adulteration in a rapid and less/non-destructive manner that can facilitate high-throughput screening. Infrared spectroscopy, Raman spectroscopy, and NMR spectroscopy and their application in the detection of seafood fraud will be discussed. The portable and handheld spectroscopic devices developed at UBC Food Safety Engineering Laboratory will be introduced as well. Finally, DNA barcoding techniques will be introduced and its application for a survey study of fish mislabelling in metro Vancouver is undergoing.
Dr. Lu received his B.Sc. (Food Science) from Ocean University of China (Qingdao) in 2007 and Ph.D. (Food Science) from Washington State University in 2011. He was a postdoctoral fellow in the College of Veterinary Medicine at Washington State University before he joined in UBC in January 2013, as the director of the UBC Food Safety Engineering Laboratory. He received tenure with promotion to Associate Professor in June 2017. He is the recipient of UBC Peter Wall Scholar (2017), the recipient of Larry Beuchat Young Research Award from International Association for Food Protection (2017), the recipient of Young Scientist Excellence Award from International Union of Food Science and Technology (2015), and currently the editorial board member of Applied and Environmental Microbiology, Journal of Food Science, Food and Agricultural Immunology, etc. He is the author of over 85 scientific papers as well as one book and several book chapters.
